急，ASP图片上传问题
本地测试中doc|xls|ppt和JPG上传都是正常都，但放到服务器上后只有doc|xls|ppt上传正常，JPG大小在50K左右以上时就超时了，而其他文件几M也正常，这是为什么啊？贴上代码：
<%@LANGUAGE="VBSCRIPT" CODEPAGE="936"%>
<!--#include file="admin_upload.INC"-->

<title>文件上传</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">

有哪位高手能告诉我到底是代码问题还是服务器配置问题啊
